7 Claims.

My invention relates to the art of knitting and it particularly has for its object to provide pile fabric such as plush fabrics or carpet fabrics which shall be substantially stretchless and can be knit on rapid fiat knitting machines without materially slowing down their operations.

It is the object of the present invention to of knitting the fabric above referred to.

Other objects will in part be. obvious and in part be pointed out hereinafter.

In the accompanying drawing:

Fig. 1 is a magnified, detail face view of a fabric according to the invention.

Fig. 2 is a detail side elevation, on a larger scale, of a portion of the structure shown in Fig. 1.

In the drawing, in which like letters of reference indicate like parts in all the figures, w indicates the threads which are knit into parallel rows of loops w and which are connected by cross-connecting threads (or inlays) i.

The woven fabric comprises threads a and b woven together in the usual way.

The pile-loop threads Z are, preferably, during the process of knitting, laid over the woven fabric and under the cross-connecting threads i. Of course the rows of loops and cross-connecting threads, during the knitting operation, are- -whole (see Fig. 3 of my Patent No. 2,155,385, is-

sued April 25, 1939).

The preferred method of making the pile fabric consists in knitting through a pre-woven fabric and during the knitting operation laying the pile threads over the surface of the woven fabric beneath the cross-connecting threads i and between the thread portions w which overlie the cross-connecting threads i, and hooking the pileloop threads through between adjacent runs of cross-connecting threads, and at the appropriate time cutting the loops to leave the piles.

Alternatively, the pile-loop threads may be laid on the woven fabric and the cross-connecting threads laid over the pile-loop threads, as the order in which the pile-loop threads and the cross-connecting threads are placed is not absolutely essential.

The kind and thickness of the pile-loop threads used, and the kind and thickness of the threads w and i, are limited. only by the capacity of the knitting machine and its ability to handle them.

The loops 1' may be cut by any approved means, either along the direction y or a: in Fig. 2, as may'be preferred.

This application relates to the method of making the pile fabric of my co-pending application, filed on even date herewith, Ser. No. 448,480. Thi application is a refiling Of my application filed December 3 1940, Ser. No. 372,642, allowed April 5, 1941.

From the foregoing description, taken in connection with the accompanying drawing, it is thought the construction, operation and advantages of the invention will be clear to those skilled in the art to which it relates.

WhatIclaim is:

1. The method of making pile fabric, which consists in knitting parallel rows of loops through a sheet of Woven fabric, cross-connecting the rows of loops by thread and placing pile-loop threads over the woven sheet in a .position between adjacent rows of loops and under the igcross-connecting thread, and looping the pileloop threads between adjacent cross-connecting thread to form pile loops.

2. The method of 'making pile fabric, which consists in knitting parallel rows of loops through a sheet of woven fabric, cross-connecting the rows of loops by thread, placing pile-loop threads over the woven sheet in a position between adjacent rows of loops and under the cross-connecting thread, looping the pile-threads between adjacent cross-connecting thread to form pile loops, and cutting the pile loops to leave piles.

3. A method of making pile fabric, which consists in knitting parallel rows of loops through a sheet of woven fabric, laying pile-loop threads on the woven fabric between adjacent rows of loops, cross connecting the rows of loops by thread and laying the thread over the pile-loop threads, and looping the pile-loop threads between adjacent cross-connecting thread to form tween adjacent cross connecting thread to form pile loops and finally cutting the pile loops to' leave piles.

5. The method of making pile fabric, which sheet in a position between adjacent rows of 15 loops, cross-connecting the rows of loops by thread passed over the pile-loop threads, and looping the pile-loop threads between adjacent cross-connecting thread to form pile loops and thereafter cutting the pile loops to leave piles.

'7. The method of making pile fabric, which consists in first knitting parallel rows of loops through a woven sheet and cross-connecting the rows of loops by thread, then placing pile-loop threads between said rows and under said crossconnecting thread, then looping the pile-loop threads between adjacent cross-connecting thread, and finally cutting the pile loops.
